Hello all,
i am building a new low power, low cost backupserver.
This build will consist of the following hardware:
1. Asrock c2550d4i mainboard with 2 x 8GB mem and 12 SATA
2. Toshiba PA4293E-1HN0 3TB harddisk 6 pieces
3. 12 bay 2u case (https://ri-vier.eu/rivier-2u-12bay-chassis-with-sas-backplane-rvs206a-p-323.html?cPath=1_3_5)
4. Seasonic 250 Watt power supply
5. Sandisk Ultra 32 GB USB3 sticks (2 pieces in mirror)
Software will be Omnios + napp-it on the USB mirror (better use the 12 SATA slots for datasets).
Yesterday i have tested the napp-it usb mirror in a HP N54 microserver.
It worked. After formatting and slicing the second stick i could build the mirror.
Resilvering took 20 minutes or so.
I do have some questions about the final setup:
a. what is the best layout for the 6 3TB disks? Personally i am thinking about one 6 disk RaidZ2 volume, but maybe 3 2 disk mirrorsets are better... The purpose of the server is backups only, so no vm storage etc.
b. can i disable synchronous writes on the backup server for more performance or does that ruin the data integrity?
The server will be used in a datacenter with UPS and Generators.
c. the c2550d4i has 2 Gbit ports (and 1 ipmi port). I want to trunk the 2 ports for more speed and redundancy, both ports will be put in 2 unmanaged interconnected Zyxel Gbit switches (so no lacp). Is that a valid network setup?
Thank you in advance for your advice.
Regards,
Dirk Adamsky
